Quizplus · Accepted Answer

The difference of two squares formula is a² - b² = (a + b)(a - b). In this case, we do not have specific numbers, but we have two terms (7 + 2x) and (7 - 2x) that have the same variable but opposite signs. Therefore, we can use the difference of two squares formula and factor it as (7 + 2x)(7 - 2x). The difference of two squares formula is (a + b)(a - b). In this case, we can rewrite the given expression as (7^2 - (2x)^2), which is in the form of the difference of two squares. Using the formula, we get (7 + 2x)(7 - 2x), which is equivalent to choice letter C.
